Prenatal Pills and Sickness

Since I found I was pregnant at 4 weeks, it been hard swallowing my prenatals. I hardly take any sort of pills to begin with. I ground them and added it to apple sauce, shakes, etc- nope, made me throw up. I found a smaller pill alternative, but I'm still sick. I've chosen to take them at night because if they make me sick, I can just sleep it off- but then my body caught the hint and started throwing them up. The pills are organic and dissolve faster than most other pills. I've felt sad and a little depressed because I've gone a week without my prenatal pill, and I've been trying to eat healthier to give my baby an alternative to the pills- still, I feel if I can't take care of my baby now, how the heck can I take care of it when it's born. I'm going into my second trimester and I'm not feeling any better. :(  Please help me ladies on what the heck to do, inexpensive alternatives, food, etc etc. Did you take the pills? If not, what did you do? How much money did you spend on healthy food a week? Help help help!
